Probably Kaitaishinso zero just because I want more of a chance for it to come the U.S. now something that NEEDS to be rehashed has to be Elfen Lied or Rave Master. Oh My God so many feels from those two manga

As for me, Nisekoi is the newest one on my list. I have recently started reading the manga and it is a ton of fun. But the big one, which is probably a long shot to ever be adapted due to music licensing costs: Sayonara Piano Sonata It is originally a light novel series and the manga was short changed and only given about 16 chapters, finishing the first volume of the light novels, but I think it still qualifies.

the main character plays the Beatles song "Blackbird" at a pivotal point in the first volume, using it to convince Mafuyu to join their club, and band.

The name she chooses is the Hungarian word for "Blackbird", which the main character doesn't figure out until near the end of the book, but when he does, he knows more about how she feels about him. When the crowd calls for an encore at their first live concert, the band leader tells them that there is only one song that they can do as an encore and sends the main character and Mafuyu out by themselves, just the lead guitar and bass player/male vocalist, to do the song as their encore.

Any other song wouldn't do, and with the number of similarly intertwined song/plot issues, it would be very expensive to do the show. That fact was even mentioned in an Omake in the manga version.
